Mars

N47°26'22.3" / E 8°31'28.1"

Mars one week before its closest aproach to Earth. Through
Zeiss 1200/150mm APO refractor with ScopeTronix 40mm MaxVue
eyepiece. Afocal with T-adapter coupling. Sensitivity
equivalent: 100 ASA. Composite picture of 22 slightly
underexposed frames. The reason for this is the wobbling
picture of Mars after passing through the dynamic atmosphere
at a low elevation angle. By using very short exposure times
blur of the picture can be minimized. The program AstroStack
auto-aligns the unsteady position of Mars in the stack of
pictures. The under-exposed pictures are added and blended
into an acceptable result. Astro
--> Look at the wonders of the sky...

Small image scale but real nice. I see a ton of features.
